Rafting was a luxury after crossing previous rivers on foot, running the risk of hypothermia or even drowning. 筏運曾經(jīng)是一種奢華的方式比起過(guò)河時(shí)用腳的時(shí)代，筏運的風(fēng)險在降低體溫或是溺死。
Icerafting deposits are formed by the melting of sedimentladen ice blocks, which is transported into sea or lake when spring is changing into summer. 冰筏沉積是負載沉積物的冰塊在春夏之交筏運到海洋或湖泊中，冰塊融化沉積物墜落所形成的。
